Examples of mirror and water reflections are shown in the figures below:

An object appears as the following image after first reflecting in a mirror and then reflecting on water:

The original object is:

A
B
C
D
Step 1: Understand the transformation sequence.
The object undergoes two distinct transformations: Mirror reflection: A horizontal flip of the original object. Water reflection: A vertical flip of the mirrored object. Step 2: Reverse the transformations.
To find the original image, reverse the transformations step by step: Reverse the water reflection (vertical flip) applied to the final image \(5:24\), resulting in: \[ 4:25 \] Reverse the mirror reflection (horizontal flip) applied to \(4:25\), resulting in: \[ h2:5 \] Step 3: Confirm the result.
The original image before any transformations is:
Final Answer: (1)





A JK flip-flop has inputs $J = 1$ and $K = 1$.
The clock input is applied as shown. Find the output clock cycles per second (output frequency).

f(w, x, y, z) =\( \Sigma\) (0, 2, 5, 7, 8, 10, 13, 14, 15)
Find the correct simplified expression.
For the non-inverting amplifier shown in the figure, the input voltage is 1 V. The feedback network consists of 2 k$\Omega$ and 1 k$\Omega$ resistors as shown.
If the switch is open, $V_o = x$.
If the switch is closed, $V_o = ____ x$.

Consider the system described by the difference equation
\[ y(n) = \frac{5}{6}y(n-1) - \frac{1}{6}(4-n) + x(n). \] Determine whether the system is linear and time-invariant (LTI).
